About the Lab
Professor Hoseong Lee's research lab specializes in advanced control systems and sustainable energy technologies. The lab focuses on developing robust motion control systems for high-precision industrial applications, integrating friction compensation, disturbance observers, and feedforward control for enhanced performance. In parallel, the lab investigates environmental sustainability in residential heating and cooling systems, particularly through life cycle climate performance (LCCP) analysis of vapor compression cycles using low-GWP refrigerants. These efforts aim to reduce environmental impacts across the entire product lifecycle.

15This paper presents a controller structure for robust high speed and accuracy motion control systems. The overall control system consists of four elements: a friction compensator; a disturbance observer for the velocity loop; a position loop feedback controller; and a feedforward controller acting on the desired output. A parameter estimation technique coupled with friction compensation is used as the first step in the design process. The friction compensator is based on the experimental frictio
Reducing environmental impacts from the energy conversion systems has been an important research topic due to recent severe global climate changes. In residential buildings, the space heating and cooling are main energy consumers, which are mainly relying on a vapor compression cycle. In an effort to better understand the environmental impacts of these systems, life cycle climate performance (LCCP) evaluation method was developed, which considers the direct and indirect emissions of the system o
